Quick question, and yes I have searched. I personally wanted to hook my A/F straight to the wire leading into the ecu as opposed to hooking it to the o2 sensor itself. This should work just the same right? I was just gonna hook it to the black/yellow wire for the rear o2 sensor, since my gauge pod is right below my cd player, and thus the ECU is very close by, and this would seem like my best option. Any Input?
